TELEDYNE HASTINGS DIGITAL VACUUM CONTROLLER WITH SET POINTS INSTRUMENTS DESIGN FEATURES The THPS 760 Plus Vacuum Controller is an exceptionally stable, accurate and repeatable absolute pressure gauge that provides excellent linearity and is unaffected by gas composition. A full 41⁄2 digit meter indicates in 0.1 Torr units from 0.1 to 1000.0 Torr. FEATURES • Range: 0.1 to 1000.0 Torr • Two Control Points • Fast Response and Linear Output • 0-10 VDC Standard (0-5 VDC Optional) The THPS 760 Plus is pictured with the HPM-760S Module. For applications where the THPM-760+ meter, controller, power supply functions are not needed, please see PB 108S for complete technical description of the HPM-760S. • Optional Instrument Configurations and Sensor Fittings • Complete Installation and Calibration Accessories APPLICATIONS For Any Situation Requiring Accurate Vacuum Measurement & Control: • • • • • • • • • • • • Cryogenics Thermal Food Containers Vacuum Furnaces Pharmaceutical Production Freeze Drying Agricultural Processes Air Conditioning Accelerators Plasma Coating Refrigeration (HVAC) Glove Boxes Appliance Manufacturing The heart of this vacum controller is the HPM-760S module, a stainless steel measurement volume attached to a small and rugged piezo-resistive transducer on a silicon chip. The chip includes a sealed vacuum reference, a resistive bridge circuit and a temperature compensation network which provides outstanding accuracy and stability. When exposed to atmosphere, the instrument measures barometric pressure. Calibration is simple, no test equipment is necessary, only an accurate barometric reading is required to set the high end. The HPS-760 power supply includes an LED digital readout and two vacuum alarm relays. Set point pressure is displayed by pressing corresponding Set Point Push Button. The display will immediately default back to measured pressure when the switch is released. The two SPDT relays are rated for 240 VAC maximum at 2A. Installation Accessories Teledyne Hastings Instruments (THI) offers a complete line of system attachments allowing for easy maintenance and contamination resistance operations. Gauge tubes are offered with various system fittings to match almost any system attachment requirement.

THPS 760 Plus® DESIGN FEATURES (cont) Pressure Measurement Range Additionally, THI’s complete line of quick disconnect attachments allows customers to install these special fittings once and then easily replace sensors without vacuum sealant or tape. For particularly dirty systems, THI offers a particle drop-out trap containing a series of nine separate baffles which prevent solid contaminants from having a direct path to the sensor’s thermopile.
